What are the different formulas in solving for power?

Answer 1

Power can be calculated using several formulas depending on the context. In electrical systems, power (P) is often calculated using the formula ( P = IV ), where ( I ) is current and ( V ) is voltage. In mechanical systems, power can be expressed as ( P = \frac{W}{t} ), where ( W ) is work done and ( t ) is time. Additionally, for rotational systems, power can be calculated using ( P = \tau \omega ), where ( \tau ) is torque and ( \omega ) is angular velocity.
